The ResellPortal phone number API lets you sell dedicated business phone numbers from your own app, website or store. Search available local and toll-free numbers in the US, Canada, the UK and Australia, buy one with a single call, and your customer gets call forwarding, voicemail and an auto-attendant. There is no monthly platform fee: each number is charged at wholesale from your wallet.
